Answer 1

$(0.3 {}^{2} + 0.2 {}^{3} ) \div 0.01 + 4.5 \div 0.3 = (( \frac{3}{10}) {}^{2} + ( \frac{1}{5} ) {}^{3} ) \div \frac{1}{100} + 15 = ( \frac{9}{100} + \frac{1}{125} ) \times 100 + 15 = \frac{49}{500} \times 100 + 15 = \frac{49}{5} + 15 = \frac{124}{5}$

Answer 2

Salut,

(0,3^2+0,2^3)÷0,01+4,5÷0,3=((3/10)^2+1/5^3)÷1/100+15=(9/100+1/125)×100+15=49/500×100+15=49/5
